Abstract

The sliding door at an elevator shaft has two panels (2,3) suspended from upper running trolleys (4,5) to ride in lower guides. On the opening/closing movements, the panels slide in the same direction but on paths of different lengths in an overlapping action. The running trolley (4) for the panel with an accelerated movement on a closing action is at the end of a fixed draw cable (8), which is around deflection rollers (9,10) fitted to the trailing panel. The deflection rollers are of different diameters, and rotate around vertical axes (11,11'). The ends of the cable are offset in parallel, secured to the trailing end of the running trolley in the closing direction so that, on a closing movement, the shorter end of the cable is around the deflection roller (10) with the smaller diameter.
